Efficiency of Coupling Targeted Temperature Management to Brain Temperature in Severe Brain Injury

2019-06-03 23:49:14 | BioPortfolio


In severe brain-injured patients, it is recommended to strictly control the fever in order to limit brain damage (objective of neuroprotection) via the targeted temperature management (TTM). In the guidelines, the target temperature is the systemic temperature, just for practical reasons (brain temperature not being monitored in most polyvalent ICU). However, in NICU, the brain temperature is monitored routinely via the Intra-Cerebral Pressure (ICP) sensor. Since in the febrile brain-injured patients the objective of the TTM is neuroprotection, it would be more appropriate to target temperature control over the cerebral temperature.

The objective of this study is to evaluate the efficacy of TTM directly coupled to the brain temperature.

Adult patients with brain injury requiring ICP monitoring (Pressio 2, Sophysa France) and fever requiring TTM (cerebral greater than or equal to 38.5 °C) will be enrolled. The TTM will be carried out according to the usual methods of the investigator's service: external cooling devices coupled with cerebral temperature (Artic Sun, Bard France), including two phases: the cooling phase (H0 to H3) and the maintenance phase (from H3 to the end of the cooling).

Two groups will be formed. In the interventional group, coupling of the TTM will be carried out to the cerebral temperature. In the control group, coupling of the TTM will be carried out to the systemic temperature measured at the bladder site.

The primary outcome will be the percentage of time during which the cerebral temperature will be measured within recommended target temperature range (i.e. 36 to 37 °C) during the maintenance phase (H3 to H12): comparison of averages. Cerebral hemodynamic parameters (ICP, transcranial doppler, and brain tissue oxygen partial pressure if available) will also be collected, in order to be correlated with the delta temperature (cerebral temperature minor systemic temperature).

No medical device will be put in place specifically for the need of the study.

Medical and Biotech [MESH] Definitions

ANESTHESIA achieved by lowering either BODY TEMPERATURE (core cooling) or SKIN TEMPERATURE (external cooling).

Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.

Damage or trauma inflicted to the eye by external means. The concept includes both surface injuries and intraocular injuries.

Brain injuries occurring over a wide area instead of specific focal area.

A device designed to stimulate, by electric impulses, contraction of the heart muscles. It may be temporary (external) or permanent (internal or internal-external).
